HARROW.

. Be it known *that I, MARTIN J. Brennan, a citizen of the United States, residing at 'Rayne, in the parish of Acadia and State of Louisiana, have invented certain new and V useful Improvements "in Harrows, "of which :the following is a specification, reference being had to the accompanying drawings.

' This invention relates to certain improvements in harrows and is an improvement on the device as disclosed in my prior Patent No. 1,-134,639,dated April 6,1915; and it is an'object of-the inventionto provide a harrow of this typewith novel and improved means for preventingthe-soil being'treated from falling out of the "harrow and thus failing to be pulverized.

It is also an ob'ect of the invention to provide a device of this general character having novel and improved means whereby the circula-ror "revolving movement 'of'the harrow proper may be attained with a minimum of frictional resistance.

The invention'consists in the details of construction and in the combinationand arrangement of the several parts of my improved harrow whereby certain important advantages are attained andthe device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings; wherein Figure 1 is a view in top plan of a harrow constructed in accordance with an embodiment of my invention;

Fig. 2 is a view in side elevation of the harrow as herein disclosed;

. the marginal portion of the device as herein embodied.

As disclosed in the-accompanying drawings, 1 denotes a beam provided at one extremity with means 2 whereby draft rigging may be suitably engaged in order that the device may be drawn over the ground.

iA'pjili cation'filefiZLpril-Ql, 1917. SerialNo. 163,620.

Disposed vertically through the beam at a predetermined point intermediate the length 'thereof'is-ashaft 3 extending upwardly from positely-directedtrunnions upon which are I mountedthewhee'ls 6 contacting with the annular plate. 7 lying uponthe upper face of the beam 1 and surrounding the ex- '*tended portion 'ofsaid shaft B'Whereby it will be perceived 'thatthe rotation of the shaft 3 will 'be effected with 'a minimum of frictional resistance.

Concentrictothe lower end portion of the hub 1 and in spaced relation thereto is the annular member 8 substantially Z-shape in clros's sectionywith the'upper flange of which is adapted to contact the gage wheel 9 mountedon theouter extremity of the arm 10 operatively'engaged, as at 11, with the annular plate 7 hereinbefore referred to. Thea-rm 10i's' disposed substantially perpendi'c'u lar to the beam 1 and is maintained in such position through the 'mediumofthe brace'rods 12'secured to the outer end portion of the arm 10 andto the beam 1 at opposite sidesofsaid arm '10.

Mounted upon the arm 10 is the weighted member 1 1 adjustable longitudinally of said arm 10 whereby it will be perceived that the action of the gage wheel 9 upon the upper flange of the annular member 8 may be regulated.

The annular member 8 is operatively tied or connected with the hub 4: through the medium of the radiating spokes 15 formed of angle iron and suitably engaged with the annular member 8 and the spokes 15 are the ground engaging members 16.

Interposed between the outer end portions of adjacent spokes 15 are the arcuate plates 17. These plates 17 are relatively broad and have their outer edges substantially in contact with the vertical or intermediate portion of the annular member 8. The plates 17 serve effectually to preventthe soil from falling out of the harrow and thus failing to be pulverized and in practice this has been found to be of especial importance. It has also been found of manifest advantage to have the arm 10 operatively engaged with the shaft 3 above the beam 1 as this arrangement permits the harrow to run lighter, work row 1s notin use. 1

structed than the form of harrow as embodied in my prior Patent No. 1,12%,639, dated April 6, 1915.

The extremity of the'beam 1 opposite that provided with the engaging means 2 has I the member, and ground engaging means operatively engaged therewith the wheel 18 which is adapted to ride upon the upper =flange of the annular member 8. It has also been found, of advantage to provide the beam 1 at a predetermined point inwardly of the engaging means .2 withv the depending bracket 19 herein disclosedas substantially U-shape in form andwhich contacts with the upper flange of the memberSwhen the har- From the foregoing description, it is thoughtto be'obviousthat a harrow constructed in accordance with my inventlon is of an extremely simple and comparatively inexpensive nature and is particularly well adapted .for use by reason of the convenience andlfacility with which it maybe-assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof'and for this reason I do not Wish to be understood as limiting myself to theprecise arrangement and formation of the several parts herein shown in carrying out my inv' ntion in practice, except as hereinafter claimed.

I 1. A harrow of the class described comprising a beam, a hub positioned below the beam andprovided with a shaft extending'upwardly through the beam and terminating thereabove, anti-friction means carried by the upper portion of said shaft and coacting with the upper face of the beam, a member surrounding thehub and connected thereto, a wheel carried by the beam and riding upon carried by said member. 2. A structure as specified in claim 1, an

, arm operatively engaged with the upper portion ofthe shaft, and a gage wheel carried by said arm and-riding upon themember. v3. A structure. as specified in --claim 2,

'meansjinterposed between the beam and arm for'maintaining said arm substantially in'a fixed position relative to the beam.
